All of Stephen King's pillows are pointed in a certain direction.

'I brush my teeth, I wash my hands. Why would anybody wash their hands before they go to bed? I don't know,' he says. 'And the pillows are supposed to be pointed a certain way. The open side of the pillowcase is supposed to be pointed in toward the other side of the bed. I don't know why.'

Michael Phelps sleeps in a chamber with air comparable to 8,500 to 9,000 feet.

It also helps Phelps increase his performance endurance and prepare himself for competitions at high elevations.

Lyndon B. Johnson divided his day into two shifts.

The president split his day into two parts in order to get more done. He usually woke up around 6:30 or 7 a.m. and worked until 2 p.m. After a quick bout of exercise, Johnson would crawl back into bed for a 30-minute nap, getting up around 4 p.m. and working into the early morning.

Johnson reportedly picked up his napping routine from his predecessor John F. Kennedy, who also broke up his day into shifts.
